DRAIN-PIPE FOR LIQUID-DISPENSERS.

Specification of Letters Patent. Patented Sept. 14;, 1920.

Original application filed October 22, 1917, Serial No. 197,854. Divided and this application filed May 5,

1919. Serial NO. 294,938.

To all whom it may concern Be it known that I, CHARLES A. TRIPP, a citizen of the United States, and a resident of lVilmington, county of New Castle, and State of Delaware, have invented a certain new and useful Drain-Pipe for Liquid-Dispensers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This invention .relatesto drain pipes of that class used in connection with liquid dispensing machines and is a division of my copending application Serial No. 197,854, filed October 22, 1917, Liquid dispensing machines.

The prime feature of this invention is the provision, in connection with the discharge nozzle of a liquiddispensing machine,means for collecting any drippings' from the discharge nozzle and convey them to and discharge them into a receptacle provided for that purpose, and preventing any of the drippings from dropping upon parts of the machine.

A further feature of the invention is the provision of means for swinging said drain pipe in the are of a circle to bring the movable end thereof into or out of registration with the discharge end of the discharge nozzle. 1

A further feature of the invention is the provision of means for raising the drip pipe for registering and engaging the'end there of with the. open end of the discharge nozzle and for lowering the same to disengage the end thereof from the'discharge, nozzle, the drain pipe, when elevated forming a closure for the end of the discharge nozzle.

V A further featurerof the invention is the provision of means for readily attaching the drain pipe with its Operating means, or

for quickly disconnecting the same therefrom. 1

Other objects and advantages will be hereinafter more fullyfset forth and pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application Figure 1 is a side elevation of a liquid dlspensing machine with parts broken out.

Fig. 2 is an enlarged detail side elevation of the drain pipe andoperating means therefor with parts broken away.

Fig. 8 is a sectional view thereof as seen on line 8--3 Fig. 2.

Fig. 4 is a detail sectional view of the drain pipe as seen 011 line 44 Fig. 3.

Fig. 5 is a sectional view as seen on line 5 5 Fig. 2.

Fig. 6 is alongitudinal section taken on line 6-6' of Fig. 5.

Referring to the drawings in which simi lar reference numerals designate corresponding parts throughout the several views, .1 indicates a cabinet such as is used in connection with the form ofliquid dispensing machine shown in my copending applicationpreviously referred to, 2 indicates a liquid containing receptacle and 3 indicates a nozzle through which the liquid is discharged from the receptacle.

As this device is designed primarily for use in conn ection with machines for dispensingbuttermilk, andas-the liquid has a tendency to adhere to the discharge end of the'nozzle so as to cause drippings, if no means-were provided to collect these drip- .pings, the machine would soon become insanitary. i I i To this end therefore, av drain pipe 4 is provided, the upper open end 5 thereof being preferably flared so that when positioned below the open end of the nozzle 3, any drippings from the nozzle willenter said drain pipe. The lower end of the drain pipe enters the cabinetll and discharges snob. particles of the liquid as may enter the drain pipe into a receptacle (not shown) concealed in the lower inclosed portion of the. cabinet.

The discharge end of the nozzle 3i is preferably provided with a recessGinto which the edgeof the flared end 5 seats when the drain pipe. is in registra'tion with the end raised and lowered by a lever 1' of the nozzle and in its elevated position, thus closing the end of the nozzle to insects and the like when not discharging liquid.

The drain pipe extends through a hearing 7 in the wall of the cabinet and is vertically slidable therethrough, said pipe having a socket 8 lined thereto in which is located the flat portion 8 of a tongue 9, the upper end of the tongue being pivoted to the lower end of a sleeve or hollow rod 10, which is in turn slidably mounted upon a rod 11 extending down from the top 12 of the cabi- 1 net, said rod 11 being rotatable.

The wall of the socket 8 (see Fig. i) is provided with a slot 13 so that the flatportion 8 of the tongue 9 may swing into or out of the socket, the socket having a trans verse pin 14 which enters a groove 15 in the flat portion 8 and locks the tongue to the socket so as to cause said drain pipe to ascend or descend with the movement of the sleeve 10. The tongue 9 is held in fixed relation with the sleeve 10 by means of a thimble 16 which is slidable on the sleeve 10, the lower end thereof, when the thirnble is in lowered position, entering the socket 8 and forming a more rigid structure. The thinible also serves to hold the pin 1% seated in the groove 15.

Should it be desired to remove the drain pipe, the thimble 1G is moved upwardly on the sleeve 10 until it passes above the pivot point between the tongue 9 and sleeve 10, when'the ton ue may be swung laterally and disengaged from the socket 8, which leaves the drain pipe free to be removed. Likewise, when it is desired to reengage the sleeve 10 with the pipe 4, the tongue 9 is swung inwardly and the slot therein again on; god with the pin 1 1', and the parts are then looked in the rigid and assembled position by again lowering the thimble 16.

The sleeve 10 and the drain pipe at are 7, one end of which is pivoted to a bracket 18 depending from the'top section 12, while the opposite end is attached to a ring 19 surrounding the upper end of the sleeve 10, by means of links 20, the ends of the links being pivoted respectively to the lever and ring. The ring is held against vertical movement on the sleeve 10 by placing collars 21 and 22 above and below the ring 19, respectively. which collars are fixed to the sleeve, while the ring may rotate thereon.

The lever 17 is rocked on its pivot for raising and lowering the drain pipe 4 by means of a cam wheel 23 which is mounted on a shaft 24 alsocarriedby the bracket 18, said wheel having in one of its faces a cam slot 25 in which travels a trunnion 26 carried by the lever 17 between its pivotal points. the slot 25 surrounding the shaft 24% .(see 2) and having a short section as noted at 27, which is set in nearer the shaft 2a a suilicient distance to draw the end of the nozzle 4: into the recess 6 at the conclusion of the operation of the dispensing machine.

In addition to raising and lowering the drain pipe, the free end thereof must be swung laterally to remove the drain pipe from below the'end of the discharge nozzle when liquid is being discharged therefrom, and'with this in view, the sleeve 10 is caused to rotate with the rod 11 by extending a screw 28 (see Fig. 5) through the collar 21 and the wall of the sleeve 10, the inner end of the screw entering anelongated channel '29 in the rod 11, thus causing the sleeve to rotate with the rod 11, although the sleeve may have free vertical movementthereof.

The free end 5 of the drain pipe is swung in the arc of'a circle to move the same into or out of registration with the end of the discharge nozzle 3 by fixing an arm 30 (see Fig. 3) to the rod 11 adjacent the upper end thereof, one end of a horizontally movable lever 31 being connected to the free end of the'arrn 30, by means of a link 32. The opposite end of the lever 31 is pivoted to the top section 12 and between the ends of the lever 31 is attached a trunnion 38wvl1ich enters a channel 34: of a cam wheel 35,=carried by-the shaft 24: and fixed to the cam wheel 23. i

. The channel 34: is so arranged that it will cause the lever 81 to move back and forth in a horizontal plane, as shown by *fulland dotted lines iirFig. 3 of the drawings, the full lines indicatingthe position-of the parts when thedrain pipe is in registration with the discharge nozzle and the dotted lines the position of the parts when the drain pipe has been turned out of registration with the discharge nozzle.

The shaft 2land the cam wheels and 35 are driven, preferably, by a motor 36, and said parts are so arranged that the movement of said drain pipe out of and again into registration with the end of the discharge nozzle is effected "with one complete revolution of the shaft 24.

\Vhen'the machine is at rest the trunnion 26 is at one end of the inset portion 27 of the cam slot 25,but instantly the machine starts operation the trunnion 26 passes into the main cam slot 25, and as said slot is of slightly greater radius than the section 27. the lever 17 will be moved downwardly and the end 5 of the .drain pipe l-lowered'out I of engagement with'the discharge nozzle 3 to the position shown by the dotted lines in At this'time the cam 'wheel 35 will have turned so as to begin the lateral movement of the lever 31, this movement beingcontinued until the end of the drain pipe has moved to the position indicated by dotted lines in Fig. 3 of the drawings. The continued rotation of the cams 35 and 23- will result, first, in returning the end of the drain pipe into registration with the open end of the discharge nozzle and then in raising the drain pipe until the flared end 5 is again seated in the recess 6, which occurs substantially at the conclusion of the operation of the parts employed for discharging the liquid from the receptacle 2.

The upper end of the drain pipe 4 is substantially S shaped so that it will not engage or interfere with the drinking vessel, placed below the end of the discharge nozzle, as the drain pipe will clear the drinking vessel 37, and likewise the drinking vessel may be readily removed from its support without interference from the drain pipe.
